CESEL SA is a private, multidisciplinary Peruvian consulting engineering firm, with a well-deserved prestige acquired through the successful development of complex engineering projects. Its high technical level, experience and business capacity are reflected in the development of multiple consulting services, such as studies, designs, assembly and works supervision, project management, construction management, factory inspections, environmental studies, etc.

It began operations in 1972, and in its early years CESEL focused more on civil and structural designs, as well as port and heavy industry projects.

Its activities quickly expanded to cover practically the entire range of engineering consulting services, mainly in the areas of hospitals and health centers, buildings, airports, road works, transmission and distribution systems for electricity, drinking water and sewage, port, maritime and fluvial terminals, hydroelectric and thermal generation, environment, mining, iron and steel, irrigation, dams and tunnels, mechanics and heavy industry, hydrocarbons, refineries, energy conservation, control and telecommunications.

Engineering is the art of using the instruments that science provides us so that, through ingenuity, solutions are generated that provide well-being and progress, respecting the environment that surrounds us.
